G.3 JBOD
JBOD, sometimes called concatenation, strings physical hard disks together to create one
larger logical disk. Blocks of data are written to the first disk until it is finished and then the
blocks are written to the second drive, and so on.
JBOD offers no extra security and no extra performance. It is useful for combining smaller
disks into a single large logical disk. There is no redundancy, but the failure of one disk
usually only results in the failure of the data on that disk.
The logical RAID volume below shows the disk drive that the operating system would see.
The physical disks show the disks that are contained in the RAID volume.
